Statewide Threat Assessment Dashboard

The Statewide Threat Assessment Report was is developed and published by the Denali Commission in 2018. The study assessed individual threats to public infrastructure associated with, erosion, flooding, and thawing permafrost in Alaska communities; Evaluate the combined threat imposed by the interactions between erosion, flooding and thawing permafrost. The study was carried out by three entities working closely with the Denali Commission. The US Army Corps of Engineers Alaska District (USACE) was responsible for evaluating threats from flooding and erosion. The new work carried out by USACE focused primarily upon flooding, because erosion was considered extensively in the Baseline Erosion Assessment (USACE 2009) for 134 communities that were also evaluated for this study. The University of Alaska Fairbanks (UAF) Institute of Northern Engineering and the USACE Engineer Research and Development Center Cold Regions Research and Engineering Laboratory (CRREL) were responsible for evaluating the risk from thawing permafrost, as well as integrating the combined threats from erosion, flooding, and thawing permafrost into an overall score. Data collection focused entirely on publicly available data and data volunteered by agencies or the private sector. No communities were visited, nor was any effort made to validate the data beyond a review by the study team for consistency and reasonableness. It is recognized that the amount and reliability of the data varies among the communities. This Dashboard visualizes the data from the report.
